WebThe crux of the problem boils down to computing the n th derivative of the function f(u) = eucosu. (Note that if g(x) = f(2x), then g ( n) (x) = 2nf ( n) (2x) .) Using cosu = ℜ(eiu) and 1 + i = √2eiπ / 4, we find f(u) = ℜ(e ( 1 + i) u) f ( n) (u) = ℜ((1 + i)ne ( 1 + i) u) = 2n / 2euℜ(e ( u + nπ / 4) i) = 2n / 2eucos(u + nπ 4) Web19 aug. 2024 · We have: f (x) = sin2x. Differentiating once wrt x (using the chain rule), we get the first derivative: f '(x) = 2sinxcosx. At first glance we may suspect that to gain …
